This invention relates to certain new and useful improvements in doorlocks especially designed for barns and garage doors and has for itsprimary object to provide a'door lock in which the lock mechanism can beoperated from the outer side of the door only after the release of acontrol` devicel on the inner side of the door.

A further object of the invention is to provide a door lock of the abovetype wherein plurality of sliding tumblers are engaged with a slidingbolt to hold the latter in a projected and locked condition with devicesassociated with the tumblers to `edect operation thereof for shiftingthem to releasing positions from either the inner or outer side of thedoor.

A still further object of the invention is to provide a lock of theabove type wherein acl cess to the sliding tumblers from the outer sideof the door is controlled by ya device` operable from the inner side ofthe door to permit the lock mechanism to be operated from the outer sideof the door only when desired,

lVith the above andv other objects in view that will become apparent asthe nature of the invention is better understood, the same consists inthe novel form, combination and hereinafter more fully described, shownin the accompanying drawings and claimed. l

In the accompanying drawings wherein like reference characters indicatecorrespending parts throughout the several views,

Figure 1 is a fragmentary front elevational view-'of a barn or garagewith the vehicle entrance door equipped with the improved lock structureand also illustrating a smaller door equipped with a key operated lock;f

Figure 2 is a fragmentary rear elevational view of the door .showing theinner face of the lock casing and the'device for controlling theinsertion yof the tumbler operating key into the loch casing at theouter side of the door; Figure 3 is a fragmentary rear elevational view,similar tov Figure 2 with the inner is also operableat face plate of thelock casing removed, the l Figure 5 isa similar rear elevational viewwith the hey-for operating the sliding tumblers inserte-d in the lockcasing;

Figur-e 6 is a vertical cross-sectional view talren on line 6-6 ofFigure 2;

Figure 7 is a vertical cross-sec`tional view taken on line (2-7 ofFigure 2gjan'd f Figure 8 isa perspective view of the sliding tumbleroperating lrey.

Referring more. in detail to the accompanying drawings, in Figure 1there is illustrated a barn or garage `1 having a vehicle door openingtherein closed by the door 2 that is equipped with the. improved loclrstructure 3, while the barn or garage 1 further` has la smaller dooropening closed by the door 4.'

The improved lockv structure 3' is shorwn in detail in Figures 2 t0 8and comprisesV a rectangular casing the door 2 in a manner as shown 1nFigure 'Twith a removableface plate 6 for the loch casing disposed atthe inner side of the door 2.

A sliding lock bolt lower end of the casing 5 and is provi-ded at itsupper edge with spaced recesses 8 separated. by lugs 9; The nose 10ofthe bolt 7 is adapted to be' projected through an opening in the endwall of the lock casing 5 for reception in a keeperV socket provided inthe doory frame 11.- "The opposite end of the sliding bolt- 7 extendsthrough the side wall of the casing 5 at the outer side of the door2 asshown inFigure1 and is pro- 7 is mounted in the OFFICE.

5 set into an opening in ill) vide-d with a, handle or gripping blocky12.

As shown in Figures 2 to 7 the open side of the lock casing 5 has anoutwardly di` rected flange 5a with anarm extension 13 aligned with thebolt '7, the arm extension 13 being provided with a slot 14; throughwhich the rod 15 carried by the handle end of the sliding bolt 7projects at the inner side of the door. It will thereforevbe seen thatthe sliding inner side of the the outer side Vof the ydoor by the handleor gripping block 12.

A pluralityrof sliding tumblers are'associated ywith the upper recessededge of the sliding bolt 7 f the` vertically Vsliding tumbler bars 16being maintained in spaced relation bolt 7 is operable fromthel door 2by the lrnob 15 and.

bythe spacer bars 17 secured tothe integralr i face plate-of theloclrcasing 5 as shownin `Figurese, 5 and 7. The sliding tumbler bars 16are of a width to be received in the spaced lugsf) atthe upper yedgerofthe `slid ing bolt 7. Willen i'he3bolt is projected las shown in Figure5, the sliding tumbler bars 16 gravitationally dropinto spaced recessesS'a'nd retainthc b'oltin its projected and locked condition.V `'llorelease the bolt from the inner side of the door 2, a short rod orsimilar ydevice `is siinultaneouslyy engaged with" all ofthegliandle'slS for elevating the tumbler ,bars to displace the lowerends i thereof from the,sliding path of movement y the inner'sicleof thedoor,

oo b

tudi'nally' groved `head vthe sliding tumbler bars ofthe sliding bolt. iy y y The release of the-slidingtnnihler bars 16 from the outer side ot'the door is accomplished by the key or operating bar shown in Figure 8,.Asshown in Figures `5 and 7, the partition `bar 17 has the edge thereofadjacent the closed ivall of `the lock casing out awa to providealignedreeesses 2() while each sli ing tumbler bar 16` is also providedon the corresponding side edge with a recess 21, the recesses 2O andf 21as shownr in Figlure 5 being=aligned With each other when areloweredinto engavement with the ysliding bolt 7. The side Wal of the lockcasing 'above the handle or gripping block 12,.as shown in Figure 6,

1s provided with any opening 22 aligned with therecesses 20 and 21. 'j yn i Thekeybar28 shown in ,Figure 8 having a. handle 24 upon one endthereof is provided on its upper edge Withspaced lugs25 deiiningfspacedrecesses 2G that are inserted through the opening 22 in thel lock casingto assume the position shown in Figure 5. It Will now be seen that .withthe key positioned asshownn Figure 5, upward `move- --mentlof the keywill 'engage the sliding tuinbler bars 16 to elevate the same todisengage thek lower ends thereof from the sliding bolt 7 and Apermitthe latter to be shifted by the gripping block12. i i' A closure plateis associated with the openig722 in the sidey Wall of, the lock cas- V p"a:` handle for each tumblery bar ex osed at ing 5 and nits positionwith respect to said openingiis controlled' by devices carried by 4theclosurey plate 27 being-,liiited i'n its `sliding movement y a pin andslot` mounting, carries a longi- 28 at the inner end thereof that isexposed'at the ,inner side of tl1"e"`dl`aorg2.;v *A bearing i upon the'ange' 5'* atfthe immer side` of the door in said groove 28 and has oneend of block 29 is .mounted the latch rod 30 pivotallysupportcd therein.The latch rod 30 is adapted to be moved npwardl on its pivotal supportfrom the positionslibvn inFigure 5 tothe position shown in Figure 4 withthe intermediate portion thereof` received in the grooved head 28 ofthey platev27 andwith the lree end received between the spaced apcrtnredlugs of the keeper 31 with which a retaining pin 32 is associated.y Itwill therefore be seen that vvhen thelatch rod 30 is engaged with, thekeeper 31, sliding movement of the plate 27 with respect to the keyentrance opening 22 to the lock casing is prevented.`

4 From the abovedetailed description of the invention, it is believedthat `the crmstrur tionandA operation thereofwill at once he apparent,it being notedthat the sliding holt 7 is operable from the inner side ofthc door by simultaneously `,disengaging the sliding tumbler barszltherefrom and shifting thc boltu by the knob 15, while the sliding boltis also operable from the outside of the door Cil closureplate 27 forthe opening 22, the lock may still be operatedroin the inside oi thedoor but operation thereof from the outside ofthe door is prevented. Itis therefore necessary to enter the barn or garage 1 through the smalldoor 4 for disengaging the latch rod 30 from its keeper to permit use ofthekey 23 from they outer side of the door. `l/Vhen thebarn or garageVdoor 2 is lockedat night, the latch rod 3() is engaged with the platehead 28, but when the vehicle,

garage ,during is removedfrom rthe barn or the day time, the latch rod30 may he disengaged from itskeeper 31 to permit operation of the lockmechanism' from the outer side of the door. y y y i y While there isherein shown and described the preferred embodiment of the presentinvention, itis nevertheless to be understood that minor changes may` bemade therein without departing from' the spirit and scope of theinvention as claimed. y
